Theburner is held or supported in place by means of hangers VV',VVflsecured to the burner and passing through the bars C and C at theirmost elevated points. 011 the upper surface of the burner is formed aslot or narrow opening Y extending the full length of the burner withthe exception of a small portion where the hangers W and VV are securedto said burner. Caps and V having openings formed centrally therethroughthrough which are passed the perforated -oil feed pipes and W of smalldiameter and secured to the caps and lV. These same oil feed pipes arelocated concentrically withinthe burner and their meeting ends nearlymeet with each other at the center of said burner. These same oil feedpipes are closed up at their inside ends, the other or outer endsextending outside of the caps XV and a short distance and fitted withright angular-elbows. Projected upwardly from these elbows areshorteroil feed pipes and which are provided with the usual globe valves theupper ends of said feed pipes leading into oil reservoirs and and fromsaid reservoirs the oil is fed to the oil feed pipes lV and W.

The burner W is provided with a curvilinear slidable extinguisher Xwhich is lined with asbestos and being so constructed as to cover up theslot or opening in the burner thereby extinguishing the fire or flames.Through openings in the extinguisher are passed the hangers W, W saidextinguisher sliding up and down onto the top of the burner. Theextinguisher is raised by means of levers X, X secured to same, passingup through the device and inserting pins through said levers to hold itup. Asbestos is interposed between the burner W and the perforated oilfeed pipes W and WW.

Y, Y, designates small quadrangular openings located at each end of theair chute R and provided with slidable doors y, y, or if preferred theymay be hinged, said doors having knobs 3 2 by which the operator maymanipulate them. When these doors are opened the burner may then belighted by the operator.

The device is moved by and operated in connection with ordinary railroadhandcars, upon which the operator stands in working the fan not hereinshown in the drawings.
